CTES035V0-G Equivalent & Substitute Parts

Part Overview

The CTES035V0-G is a unidirectional transient voltage suppressor (TVS) diode manufactured by Comchip Technology, designed for general-purpose overvoltage protection in surface-mount applications. This component features a 5V reverse standoff voltage with a 10V maximum clamping voltage and 17A peak pulse current capability in an SOT-23-3 package.

The CTES035V0-G is classified as obsolete. Identifying qualified substitute components ensures continued availability for new designs, repairs, and production continuity where this part is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CTES035V0-G is determined by the following critical electrical and mechanical parameters:

• Reverse Standoff Voltage: 5V nominal
• Package Type: SOT-23-3 (TO-236-3, SC-59)
• Unidirectional Configuration: 2-channel Zener TVS diode
• Clamping Voltage: Maximum 10V at peak pulse current
• Peak Pulse Current: 17A at 8/20µs waveform
• Mounting Type: Surface Mount
• Regulatory Compliance: ROHS3 Compliant

The PESD5V0S2UAT,215 from Nexperia USA Inc. qualifies as a substitute based on matching reverse standoff voltage, package compatibility, unidirectional channel configuration, and regulatory compliance. Both components are rated for general-purpose transient voltage suppression in identical package geometries.

Parameter Comparison

Engineering Selection Recommendations

The PESD5V0S2UAT,215 is an active-status substitute for the obsolete CTES035V0-G. Both components meet ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new production and legacy support applications.

The substitute exhibits a higher clamping voltage (20V vs. 10V) and slightly lower peak pulse current (15A vs. 17A). These parameter differences require circuit-level evaluation to confirm compatibility with the original application's overvoltage protection requirements. The extended operating temperature range (-65 to 150°C) of the substitute provides broader thermal performance capability.

Both components are packaged in mechanically equivalent SOT-23-3 footprints, enabling direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the PESD5V0S2UAT,215 be used as a direct replacement for the CTES035V0-G?

A: Both components share identical reverse standoff voltage (5V), unidirectional 2-channel configuration, and SOT-23-3 package geometry. However, the substitute exhibits higher clamping voltage (20V vs. 10V) and lower peak pulse current (15A vs. 17A). Compatibility depends on whether the circuit can tolerate these parameter differences.

Q: What is the significance of the clamping voltage difference?

A: Clamping voltage determines the maximum voltage transient that the TVS diode will suppress across the protected circuit node. The PESD5V0S2UAT,215 clamps at 20V compared to the CTES035V0-G at 10V. If the original design requires clamping below 20V, this parameter difference must be evaluated against circuit protection requirements.

Q: Are the packages physically identical?

A: Both components use SOT-23-3 package geometry (also designated TO-236-3 or SC-59). The physical footprint and pin configuration are compatible, allowing direct board-level substitution without PCB redesign.

Q: What is the product status significance?

A: The CTES035V0-G is obsolete, meaning Comchip Technology no longer manufactures or supports this component. The PESD5V0S2UAT,215 is active-status, ensuring ongoing availability, technical support, and supply chain continuity.

Q: Do both components meet the same regulatory requirements?

A: Yes. Both the CTES035V0-G and PESD5V0S2UAT,215 are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.
